Attachment: Screen shot

Bug 950800 introduced (exposed?) a bug on the unagi, where colors are displayed incorrectly when HW composing is enabled. A screen shot is attached. Animations have correct colors, but static images seem to have incorrect component order.

The patches in bug 947504 are supposed to disable hwc by default on devices that don't support it. What device are you using? Does is still show this issue with the patches in bug 947504?

I pulled the latest ref of Gecko and Gaia, which contain the patches from bug 947504, but the bug persists.

I use an old Unagi. After flashing the device, HW composing is enabled (layers.composer2d.enable is true), even though ro.display.colorfill is not set. With the latest refs, the colors of the home screen are normal, but the buttons still flash yellow. Turning off HW composing makes the problem go away.

Did you reset the gaia profile? The trick here is that once the gaia profile has been created the hwc setting persists. In this case it may have been enabled from before the patch. Can you try wiping the gaia profile/settings and see if hwc is still turned on by default?

Sorry for the delay here. I've been traveling and couldn't test.

I cleared all settings in gaia and rebuild. Everything seems to work fine now. Thanks!
